[QUOTE="squeak9798, post: 1253916, member: 555320"] The load would be a 2ohm load No, the sub is technically a dual voice coil, 4ohm/coil load by itself. How you wire those two coils determines what the final impedance will be No, paralleling two 4ohm voice coils = 2ohm final load It's per coil. And each 4 does not go to 2 (whatever that means). You have two 4ohm loads....wiring them in parallel results in a 2ohm final load. The individual coil's impedances don't change. You still have two 4ohm coils. But wire them in parallel and you now have a single 2ohm load. Wire them in series and you have a final 8ohm load. That depends on how many subs you are wanting to use. If you are wanting to use two subs, then you will need two DVC 2ohm/coil subwoofers. Wire the coils in series-parallel and you have a final 2ohm load: [IMG]http://www.rockfordfosgate.com/rftech/wiringwizard/2_2ohmDVC_2ohm.gif[/IMG] If you are using a single subwoofer, then you will want a DVC 4ohm/coil sub and wire the coils in parallel: [IMG]http://www.rockfordfosgate.com/rftech/wiringwizard/1_4ohmDVC_2ohm.gif[/IMG] [/QUOTE]
